Abstract

A communication terminal measures the quality of reception, and reports to a base station on the results of measurement. The base station switches the transmission rate based on the reported results. When the reception quality of the communication terminal lowers, the transmission rate is switched. The transmission rate is also switched so that the interference to another may fall within an allowable range depending on the state of the channel between the communication terminal and the base station.
